2 main points, as follows:
1) This map made me remember how amazing this DLC is
2) I love the simple design.
Sure, The Angry Tests go really far, but this has a couple of neat little puzzles, with plenty of space left to add improvements. Maybe add a little puzzle to the lightbridge space. Maybe one to activate the bridge itself so you can pass.
For a first map release, very sweet. And it reminded me to upload a few of mine too :D
